just tested this out for myself using a demo of studio one this evening, and it is mind mindbogglingly good!
select a track on either the hardware or the mixer.. follows...
pan on either, they follow
change a level on either, they follow!

Its odd how cubase was one of the first to support the basic integration (auto track naming) but yet one of the last to not have full integration.
I wish now I would of saved my money on the 8.5 - 9 upgrade, and cross-graded to studio one.
i also like in thh s1 mixer how it shows gain reduction in the level meters... nice touch! wish cubase had that (im sure there is a feature request already)

Im gonna give steinberg until 9.5 if its not coming/announced by then, I doubt very much ill be buying that upgrade.

Steinberg should open up the SDK for remote controllers so that any vendor or community could do integration
on any device. (And stenberg should host a server for community drivers.) Now you need to sign a NDA
to access this functions so there will never be a community "help your self" solution for all the nice hardware
that does not really work well with steinberg software. This obviously not good for steinberg but i think yamaha
prefer less competition.

I think all DAWs should have some kind of interface allowing for hardware controllers, including iPads etc., to get information from and send control messages to the DAW. It currently works with MCU, but should be also be able a to handle broader selection of devices.

I really, really love Cubase ... but I'm stopping at 8.5 for now, sampler be damned. If this integration doesn't come along within the next 6 months or so, I'm definitely jumping to Studio One, Presonus Faderport Eight and Console 1 MKII for all my UAD plugins.

You know these threads are reviewed and it kills me that we can't get a "we are considering this for future development:" or, "we have no plans to implement this at present;" or, "this is already on our development/ upgrade priority."

Come on Steinberg, the new addon's and changes in Cubase 9 are truly great.Especially the main project window having a Similar workflow to Studio one and in some cases bettered it, all making your users create better music and more quicker to. But Console 1 makes music production even quicker used with Cubase and other Daw's it's just that good. The big deal breaker for us is not having track follow, it breaks up the flow slows you down with the constant checking to see if your on the right track in Cubase before you start editing is a pain. I haven't upgraded to Cubase 9 although the improvements is clearly worth it. I'm just gonna wait and see if your going to implement Track follow in the next update. If it doesn't happen i'm of to Studio One. If you are bigger than Studio One and Sonar who have both added Track follow to their Daw's then clearly you would follow suit. Come on Steinberg keep your customers happy and in turn you keep your customers, it's good business ethics.
